(Yes, this was almost 3 years ago. Sorry for a long delay.) The .ONESHELL feature is now supported on MS-Windows, for the default Windows shell (cmd.exe) or compatible replacements, in the development version (commit e56aad4). I realize that one of the important use cases for .ONESHELL is to use a shell that Make knows nothing about, but as such shells are not yet supported by the Windows build, I didn't feel it was right to postpone .ONESHELL any longer. Volunteers are welcome to contribute support for foreign shells. _______________________________________________ Make-w32 mailing list Make-w32@gnu.org https://lists.gnu.org/mailman/listinfo/make-w32
